Abstract

The invention relates to a water-based elastic rubber paint and a preparation method thereof and belongs to the technical field of paint. The water-based elastic rubber paint comprises, by weight, components A and component B, the components A include 30-40 parts of waterborne polyurethane emulsion, 0.3-0.6 part of water-based dispersing agents, 3-6 parts of color paste, 3-5 parts of extinction powder, 5-10 parts of elastic powder, 2-5 parts of hand feeling auxiliaries, 0.2-0.5 part of wax powder, 0.2-0.4 part of flatting agents, 0.1-0.3 part of defoaming agents, 1-2 parts of hydrated magnesium silicate, 0.5-1 part of neutralization agents, 1-2 parts of cosolvent and 5-10 parts of deionized water, the component B includes hexamethylene diisocyanate (HDI) hydrophilic isocyanate, and the weight ratio between the components A and the component B is (8-12) :1. According to the water-based elastic rubber paint and the preparation method thereof, pure waterborne system raw materials are used for preparing the water-based elastic rubber paint, the water-based elastic rubber paint is excellent in hand feeling elasticity and resistant to ethyl alcohol scrubbing and RCA paper tape friction and can be rubbed by RCA paper tapes for 200 times.

Description

[0001] technical field [0002] The invention relates to a water-based elastic feel paint and a preparation method thereof, belonging to the technical field of paints. [0003] Background technique [0004] Under the pressure of smog, the National People's Congress revised the Environmental Protection Law for the first time in 25 years. The revision of the "Environmental Protection Law" was passed, which increased the punishment of large polluters. The amendment clearly stipulates that polluting enterprises can be punished according to the original The amount is continuously punished on a daily basis. Especially in the electronics industry, the environmental protection requirements for the surface coating of products are more stringent. [0005] Nowadays, the requirements for the appearance effect of daily necessities are getting higher and higher, such as aluminum powder effect, crack effect, elastic feel effect, etc., especially for some parts that are often touched by ...
